8 Claims.

This invention relates to improved apparatus for supporting a limb of a bed patient relative to the bed during intravenous administrations, the primary object of the invention being to provide a more practical, simplified, lightweight and more efiicient device of this character which can be more easily installed, adjusted and used by nurses and others without exertion of unusual strength and continued effort before, during and after intravenous administrations.

Another important object of the invention is to provide a device of the character indicated above which installs more easily and securely on a bed rail and spring side member, and which is more completel and readily adjustable to more efficiently and comfortably support the patients limb.

Other important objects and advantageous features of the invention will be apparent from the following description and the accompanying drawings, wherein, for purposes of illustration only, a specific embodiment of the invention is shown in detail.

In the drawings:

Figure 1 is an outboard side elevation showing the device in use;

Figure 2 is a top plan view of Figure 1 Figure 3 is a transverse, vertical section taken on the line 33 of Figure 1;

Figure 4 is an inboard perspective View of the frame;

Figure 5 is an outboard side elevation showing an adjusted position of the limb shelf;

Figure 6 is a transverse, vertical section taken through the frame of the device and through tubular bed frame side members, showing special clamping elements therefor.

Referring in detail to the drawings, wherein like numerals designate like parts throughout the several views, the illustrated device comprises a longitudinally elongated, vertical frame 1 comprising flat, vertical ends 8 and 9 joined at their upper and lower ends by fiat, horizontal and parallel upper and lower longitudinal members I and II, respectively. Vertical plate members 12 and [3 are secured along the ends 8 and 9, respectively, at their inboard edges, and vertical, longitudinal plate members l4 and l are secured along the facing sides of the longitudinal members Ill and II, respectively, at their inboard edges. A vertical cross member I6 is secured on the outboard side of the longitudinal plate members I4 and i5 midway their ends and formed with a vertically elongated slot H. In vertical alignment with the slot I! a perpendicular tube l8 positioned in an opening l9 in the upper 1ongitudinal member ID is secured to the outboard side of the upper longitudinal plate member l4, the tube I8 being provided with a threaded hole 20 near its upper end to accommodate a set screw 2! having a cross bar handle 22.

On the inner side of the frame end 9 is secured a vertical tubular socket 23 opening at its upper end through the upper longitudinal member ID. Projecting beyond the inboard side of the frame 1 are fixed bed frame engaging hooks 24, each comprising a horizontal portion 25 secured to the inner edge of a respective one of the vertical plate members I2 and i3 on the frame ends 8 and 9 and a right angular, downturned terminal 26. i Projectable through the slot ll of the vertical cross member 16 is a bolt 21 having on its inboard end an upper bed frame engaging hook 28 which is reversible from the position shown in Figure 3, to the position shown in Figure 6, for use with angle iron bed frame side members and tubular or round bar bed frame side members, respectively.

The hook 28, as shown in Figure 3, comprises a plate having a vertical projection 29 to engage the inboard surface of the vertical flange 3|] of the upper angle iron bed frame side member 3|, with the lower hooks 24 resting upon the lower bed frame angle iron side member 32, the inboard side of the frame 1 engaging the outboard sides of the bed frame side members 3| and 32. The hook 28 further comprises a crook 33 opposed to the projection 29 and offset inboardly therefrom. In Figure 6 the projection 29 is free of both the upper and lower tubular bed frame side members 3la and 32a, while the crock 33 is engaged under and behind the upper tube 3Ia. The bolt 21 has a handwheel nut 34 on its outboard end arranged to be tightened against the outboard side of the cross member 16 to secure the hooks in engagement with the bed frame side members and mount the device at the desired location along the side of the bed.

Removably inserted in the socket 23 is the offset lower end 35 of the rod mast 36 having a lateral hook 31 on its upper end for suspending a transfusion container 38 or the like. I

The limb support of the herein illustrated device comprises a horizontally elongated shelf 40 made of plywood, metal or other suitable material in concave-convex cross-section, with the convex bottom and sides having several transverse rows of perforations 4| therein to permit easy stitching on of surgical padding 42 and convenient replacement thereof. Straps 43 are distributed along the shelf 40 at spaced intervals and consist of strap elements 44, 45 secured to opposite sides of the shelf and connectible by suitable buckles 46. The shelf 40 is supported by a frame comprising an elongated horizontal bar 40' terminating at its ends in standards 41' and inboardly projecting arms 42' to engage under the convex shelf bottom, to which the arms 42 are secured by bolts or rivets 39. A protective wall plate 41 is secured to the standards 4| to rise from the outboard edge of the shelf 40 and extends in spaced relation to the opposite ends of the shelf and a semicircular clamp element 49 is secured to the outboard side of the middle of the bar 40', and has radial serrations 50 thereon and a centered bolt projecting therefrom.

The bolt 5| passes centrally and-freely through another semicircular clamp element 52 having cooperatin radial serrations 53 engageable with the serrations on the clamp element 49 when the clamp element 49, and hence the shelf 48, is tilted or rocked on the axis of the bolt 55, when the wing nut 54 on the bolt 5| is loosened and is retightened to clamp and retain the elements 49 and 52 together in a new angular relation.

The clamp element 52 is rigid with the offset upper end 55 of a heavy bar or rod 56 which is slidably inserted downwardly in the tube IS, whereby the shelf 40 is supported for rotational or swinging adjustment on a vertical axis and can be raised and lowered, the desired adjustment being retained by tightening the set screw 2!.

The upper part of the rod 56 has a rigid inhoardly projecting stabilizing arm or bracket 5 curved to conform enerally to the convex bottom of the shelf 40 and freely engageable therewith. The purpose of the bracket 57 is to prevent the shelf 40 from dropping if the clamp elements 49 and 52 are loosened more than necessary and to assist in angular adjustment of the'shelf 40 by preventing binding due to inboard or outboard tilting of the shelf 40, while the clamp assembly is loosened.
